Liang-Chi Hsieh closed SPARK-18824. ----------------------------------- Resolution: Won't Fix > Add optimizer rule to reorder expensive Filter predicates like ScalaUDF > ----------------------------------------------------------------------- > > Key: SPARK-18824 > URL: https://issues.apache.org/jira/browse/SPARK-18824 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Liang-Chi Hsieh > > During evaluation of predicates in Filter, we can reorder the expressions in > order to evaluate the more expensive expressions like ScalaUDF later. So if > other expressions are evaluated to false, we can avoid evaluation of these > UDFs. > We can add an optimizer rule to do this optimization. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
